This invention relates to improvements in door hinge structures and more particularly, in hinge structures for doors which, when released, are to automatically return to a ceri .5ta-in definite position, either open or closed.

The general objects of the presentinvention are to providepan improved door hinge structure having simple and improved parts capable of inexpensive manufacture and convenient assembly and disassembly; in which adjustments can be simply and quickly made without disassembly of parts; and which is positive in action Vand not likely to get out of order in service.

Further objects of the invention are in part obvious and in part will appear more in detail hereinafter.

The invention will be readily understood from the following description thereof, taken in connection with the accompanying drawing in which Y Fig. 1 is a central vertical sectional View on the line 1-1, Fig. 2, a part only of the door post being in elevation; Fig. 2 is a view in end elevation of parts of the upper and lower hinge connections and in vertical section through the door; Fig. 3 is a perspective lview of the cam member of the lower hinge connection; Vand Fig. 4 is a cross sectional view 30 Ythrough the door post, on the line 4-A4, Fig. 1.

In the embodiment of the invention here illustrated, A represents'asuitable door post to which a door B is hinged, said post and said door being of any desired construction. The post here shown is of sheet metal with a longitudinally disposed Channel or groove 1 in each of the four sides thereof. y f

Hinge connections are provided between 'the top of the door and said post and between the bottom of said door and said post, as is usual, the hinge connection .in each case lcomprising two cooperating hinge parts, 'ha stationary part secured to the door post and a movable part secured to the door.

Aconnection includes a one-piece hinge pintle having an upper endportion 5 of generally cylindrical form, a lower end portion 6 of non-circular shape in cross section and an intermediate collar 7 of generally annular The movable hinge part of the upper hinge n form. Said lower, non-circular pintle portion is adapted to t a correspondingly shaped, vertically. disposed opening 8 in the top portion ofthe door and the pintle collar y 7 is adapted to vrest upon said door top por- 55 tion.' To firmly secure the pintle to the door,

a suitable anchoring plate is provided, said plate having a' generally rectangular top portion 13 anda pair of correspondingly shaped depending flanges 14 adapted to ex- 60 tend alongside the door sides and secured to vthe door by one or more bolts'l extending through said door' `and said plate flanges. Sald plate top portion is providedinterc mediate its ends with an upward offset 16 to 65 provide therebelowV a cavity or recess 17 for the pintle collar, said offset being provided with a circular opening 18 through which the upper cylindrical portion 5 of said pintle j extends. v a "7:0 .The stationary hinge'part of the upper hinge connection includes a one-piece socket member 20 having a vertically, disposed, generally cylindrical socket 21 adapted to receive the cylindrical upper end portion of the pintle of the movable hinge part. Said socket member is also provided with a generally rectangular base portion 22 fitting and secured within a channel 1 of the door post Y A by 'one or more bolts 23 extending through so said post andthrough said base, portion.A

The stationary hinge part of vthe lower hinge connection includes a bracket having a vertically disposed generally yrectangular vsecuring portion 30 and a generally circular *85 Asupporting portion 31 extending? outwardly at right angles from the top of said 'securing portion,` saidy portions being connected at their sides bywe'bs 32 (for purposes ofA Y strength). SaidA bracket `securing portion fits andis secured within achannel or groove 1 of the door post A by oneor more, bolts 34 extendingV through said post. andvthrou'gh said securing portion. V Mounted upon the 95 Aupper surface of the supportingportion of -downwardlyin opposite directions, as' at 36 and 37, froma highdwell orcstoppoint 38 "ico to a low dwell or stop point 39 diametrically opposed thereto.

Said cam member is provided at its base or lower end with an outwardly extending annular flange 40 and with an inwardly extending annular flange 41, the latter being engaged by the non-circular head 42 of a hollow bolt having its shank 43 extending downwardly through a centrally disposed aperture 44 in the bracket supportingY portion 31. The sides of said boltV head are engaged by the portions 45 of said cam member, which portions form a non-circular recess for said head and effectively prevent turning of said bolt. A nut 46Y is threaded on the lower projecting end portion of said bolt shank and by screwing up said nut, said cam member is firmly secured upon said bracket supporting portion, as will be readily understood.

The movable hinge part of the lower hinge connection includes a one piece pintle having a generally cylindrical body portion 51, a reduced upper end extension 52 of non-circular shape in cross section and a reduced lower end extension 53 of generally cylindrical' form. Said non-circular top extension 52 is adapted to lit in a correspondingly shaped opening 55 inv the door B and said cylindrical bottom extension 53 is adapted to lit or seat in the correspondingly shaped opening 56 in the bolt 43 which securesI the cam member 35 on the bracket supporting portion 31. Said pintle body portion, near its lower end, is provided with a laterally extending tapering boss 60 terminating in a reduced stud 61 on which isl rotatably mounted a ball-bearing roller 63 for movement along the cam Ysurfaces 36, 37 of the cam member 35. Said roller is held on said stud by a screw 65 threaded into the end of said stud and having its headv 66 engaging said roller, as clearly indicated in Fig. 1.

Preferably and as shown, the lower hinge connection includes a wear-resisting door plate similar to the anchoring door plate of the upper hinge connection. The door plate of .said lower hinge connection includes a generally rectangular wear-resisting body portion 70 extending along, the lower edge of the door and two upwardly extending, correspondingly shaped flanges 71- extending along the sides of the door and secured to the door by one or more bolts 72 extending through the door and through said flanges. The plate body portion 70 intermediate its ends is, of course, provided with an opening 73 through which extends the vnon-circular upper pintle extension 52.

To conceal the working parts of the lower hinge connection, with consequent improvement in the appearance thereof, aninvert'ed cup shapedenclosing cover member ispro* vided, saidmember enclosing said cam member, the pintle body portion 51 and the roller vcooperating hinge parts, there being a sta- 63 carried thereby. The lower end of the tubular side wall kof said enclosing member rests upon the bracket supporting portion 31 and surrounds and is rigidly secured to the outwardly extending base flange 40 of the caml member 35, such as by the screws 81. The circular top portion 82 of said enclosing member may be provided with one or more upwardly odset portions 83, for appearance purposes or otherwise, andis of course-,also

provided with a centrally disposed opening 84 for the upper end of the cylindrical pintle body portion 51.

When thedoor B ,is in its normal position, either open'or closed, the roller 63 rests in the low dwell orstop point 39 of the cam member 35;L NMovementfof the door from this'norm'al Vposition causes the roller to ride'up either the cam surface 36 or the cam surface 37, depending .upon which direction the door is' swung. The door is, of course, raised during such movement but, as indicated in the drawing, ample space is provided between the two hinge parts of the upper hinge connection for this vertical movement of the door. When the door is released, it auto- .l

amount to bring the'low cam dwell 39 to the desired position, as will be readily` understood. The door need ,not be removed or the -parts of the lower'hingeconn'ection disassembled. f f

AForconvenience of manufacture andassembly, the door openings 8 and 55 correspond in size, shape and location, as do the pintle portions`6-and 52. This enables either 1 end of the door to be positioned at the top, as will be readily understood. i
